Combining unsaturated metal sites and narrow pores within a Co(II)-based MOF towards CO2 separation and transformation

A Co(II)-based MOF, {[Co3(L)2(bpb)(DMA)(H2O)]·Solvents}n with a unique interpenetrated framework, have been solvothermally prepared. Moreover, due to its unsaturated metal sites and narrow pores inside the framework, RH-1 reveals excellent selective CO2 adsorption over N2 and CH4, and good performances in catalytic CO2 conversion to cyclic carbonates under mild conditions.
